Deaf dog learns sign language

A Nebraska animal shelter is facing a new challenge: the addition of two deaf dogs. But employees at the shelter — and the dogs — are rising to the challenge. Rosie, a 4-year-old pit bull mix, is learning sign language and has already mastered the signs for "good girl" and "sit."

For 9-month-old Noah, help comes in the form of another dog who's helping him learn how to behave.
